An aside that I was curious about: "20H1"?

I found https://blogs.windows.com/windowsexperience/2020/06/16/whats...:

> Windows 10, version 20H2 is, therefore, “20H2” because it will be released in the second half of the 2020 calendar year.

So 20H1 is 2020 1st half then. And Windows now has biannual rolling release? Nice.
